Octacosane is a compound often used in organic chemistry.

I like climbing Mount Rakukiyama.

He arrived in Tokyo yesterday.

He is good at reading piano music.

He drinks a special beverage every day for his health.

I am planning to go to the American consulate tomorrow.

Ryota is my best friend.
